thanks for posting the photos. First, I feel like there is a mix of styles in the design that aren't really complementing each other. The waterfall walnut frame around the frig and wall oven areas is VERY modern. But the rounded front cooktop/bar, the divided light glass front cabinet doors, and molding on the upper cabinets are very traditional -- maybe even a bit 'cottage'. The looks are fighting each other IMHO. Also, I would reconsider the placement of the wall ovens -- they seem very crowded back in that corner. And the range hood going to the ceiling but the cabinets stopping short looks odd to me. Maybe a different hood with a narrower chimney would look better. And, is that the dishwasher on the island? --- Yikes -- I would want that right next to the sink (otherwise you'll be dripping water all over the floor everytime you load it)

Ok, first of all I think we have very similar tastes because I looked at the pics you tagged in your idea books, but this layout is not efficient at all. your working triangle is non existent and I think there is way too much crowded in one corner. The island is staring out into nothing, and definitely needs to be rotated 90 degrees and I think the shape looks like something you would see in a bar. I am currently doing my own kitchen in two shades of painted cabinetry and will post my drawings and actual images, and then some images that you might like. I think the sink and DW need to be in the island. The fridge needs to be integrated to avoid this much stainless steel since you clearly like a more eclectic, non modern look, and the hood can be more elaborate. I personally think a 48" range with a dramatic hood on that back will with the island turned the correct way will be a nice focal point for your kitchen. You could also do a microwave drawer in your island, that way you only see the range from the front. Also, where is your pantry? Where are you storing food? The second image is a range hood you will probably like The third and fourth are drawings of my kitchen, and the first is a painted on painted kitchen with whimsy you might like. I will attach photos of my project on an additional feed since 4 photos is the limit.

North facing kitchen with only one wall & 1 window on same wall. I have a walk in pantry. I have lots of space for an enormous island.

I love the tall units but you need to go straight to the ceiling to prevent dust and dirt settling on the top. I would put a row of small up and over cupboards along the very top as an option. Very handy for unsightly bulky items. I don't like the end open shelves by sink very dated but what you could do is a long double shelf all the way along the island with a wine racking either side for balance vertically. I think shelving each side of the sink would be better. You have a lot of cupboards but no deep drawers which are highly valued these days. Good selling point. I Like your colour suggestions... The little Greene paint company have a lovely grey so does farrow and ball. Where are you sourcing your Quartz and what flooring? Do your ovens have easy open shelf doors ..handy as they retract so don't get in the way as you take food out..Neff offer best ones. If you want a better balance of tall you could always do fridge freezer one side and pull out pantry on the other with racking. Then on sink side don't go all the way along the wall just have it as centred space so you can pull out larder doors. On your island you will need your bin as this'll be prep area? What is the room opposite tall cupboards? Need the island to look good from that side as that is what you will see. Hope of help. I'm embarking on the same thing and have spent hours and hours researching!
